[Don't regret it] Revealing the principle and use of magnetic powder brake
Magnetic powder brake is based on electromagnetic principle and uses magnetic powder to transmit torque. It uses magnetic powder as a medium, and a new transmission element that forms a magnetic powder chain to transmit torque when energized. It is mainly composed of an inner rotor, an outer rotor, an exciting coil, and magnetic powder. When the coil is not energized, the driving rotor rotates. Due to the centrifugal force, the magnetic powder is thrown on the inner wall of the driving rotor. There is no contact between the magnetic powder and the driven rotor, and the driving rotor is idling. After the DC power is connected, an electromagnetic field is generated, and the magnetic powder of the working medium forms a magnetic powder chain under the action of the magnetic field lines, connecting the inner rotor and the outer rotor to achieve the purpose of transmitting and braking torque.
The specific uses of magnetic powder brakes are introduced below:
1. Suitable for constant tension control systems, such as printing machines, slitters, laminating machines, coating machines, paper machines, wire drawing machines and cable winding machines, as well as processing equipment and textile machinery such as sheet metal, strip, film Wait.
2, stepless speed regulation, coupled with sensors and control lines can achieve stepless speed regulation, especially for high-speed speed fine-tuning and small and medium power speed control system.
3. The magnetic powder brake is used as an overload device, which is used as a loading device for torque measurement in power machines such as engines, electric motors, electric structures, hydraulic components, and reducers.
4. During overload protection, when an accident occurs in the working system and the torque is overloaded, the clutch automatically slips, thereby protecting mechanical equipment and motive power.
Facing the various professional brakes existing in the society, the development of magnetic powder brakes also faces relatively large challenges. The magnetic powder brake produced by Hailing Magnetic Powder through technological innovation has a simple structure principle, more convenient use, and wider use. The market received rave reviews.
